March for Life, the pro-life advocacy group, is noting the 45th anniversary of its founding with its annual march, this year set for Jan. 19, according to the Washington Examiner.

The group was formed to protest the 1973 Supreme Court decision in Roe v. Wade that legalized abortion.

The march, to be held in Washington, D.C., is expected to draw over 100,000 people, the Examiner reported.

The Guttmacher Institute, which supports legalized abortion, reported in January that the legal abortion rate in the United States has fallen to 14.6 abortions per 1,000 women, the lowest recorded rate since the Roe v. Wade decision, according to NPR.

The number of abortions has been declining every year since a 29.3 per 1,000 women peak in 1980 and 1981, NPR reported.

On Dec. 20, the group announced its lineup of speakers for the march, which will include Pam Tebow, mother of former NFL star Tim Tebow; U.S. Reps. Dan Lipinski, D-Ill., and Chris Smith, R-N.J., according to a March for Life press release.
